j Application ined Augustin, isa?. sei-iai (no. maeva This vinvention relates to presses, and its general object is to provide a fruit juice dispensin machine that is adapted to receive whole fruit7 and includes means for rendering the fruit to` pulp with pressing means for the pulp to obtain its juice, and dispensing means for the juice.

A further object ofthe invention is to provide Va fruit juice dispensing. vmachine ofthe character above set forth, that is sim le in construction contains few parts'- is semi-automatic in operation and is eilcient in operation and service. -c rllhis invention also consists in certain other features of construction and in the combination andy arrangement ,of the several parts, to be hereinafter fully described', illustrated -in the accompanying dr-awings and-specilically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several` views, and inv which:

`Referring to the drawings in detail the reference numeral 1 indicates a platform providedA with a front 2 and may have sides 'depending therefrom to forml a counter or other like supporting means. j

.Supported upon ythe platform 1 through the instrumentality of legs 3 is ak container' 4 having a spigot 5 for dispensing the contents of the containerv Disposed about lthev .inlet end lof `the spigot 5 is a screen 6 vfor a purpose which will be apparent.v An out-let valve 7 isfalso disposed in communication ,withthe container below the spigot so that the container can be completely emptied if desired.

Rising from the forward end of the platform 1 are uprights 8 whichhave securedv to their upperends spaced parallel channelv guidesQ having rollers'l() disposed inthe bottoms thereof as. best shown in Figure 3 ing their ends journaled in the walls thereof are `spaced parallel shafts 16 having secured thereto toothed rollers 17 which cooperate-to receive fruit.v therebetween for j grinding and crushing up the latter as .will be apparent. @ne of the shafts 16 projects a considerable distance beyond the body 13 secured to this projecting endis a pulley.

18 whichreceives a belt 19.- The belt 19 islikewise received by a pulley 20 securedto the [shaft of a motor 2:1 asfshown. By this construction, thebelt 19 will drive the pulley carrying shaft Aand due to the engagement.:

of the teeth of the drum of this shaft with thev teethv of the drum of the other shaft7 it will be obvious that bothof the drums will be rotatedi and crush fruit therebetween as aboveset forth. y

. compression chamber is arranged inthe containerl 4 and includes an enlargedfpoi'- tion 22 wholly disposed inl thecontainer, and a relatively'small port'ion23v which passes through;y the bottom of the container and terminates below the platform 1" as shown in Figure l. 'The enlarged portion of-the chamber is provided with .a .plurality'rof openings disposed in its vertical walls thereof. vand arranged for slidable movement in the enlarged portion 22 is a piston head 24..

which `has depending therefrom a rod- 25 and said rod is secured kto a4 piston 26 *disposed in the small portion 23 for slidable movement as will be apparent.V 4The 26 is provided with an "expansion ring; 27. `h/lounted on the rollers 10 for slidableV movement inthe channel guides 9 isa platel 28 which is .provided with a flanged top and a recessed bottom. Secured to one of the end edges ofsaid plate are a pair of cables29 having weights `3() liXedy thereto andv said ller position as shown inFigure 1, and in order to retain the plate 28 in its normal position against the pull of theweights 30, I provide a latch which includes a hook portion 43 normally engaging a iange of the plate as shown, and extending in opposed relation with respect to the hook portion 43 is a lever 44. The latch is pivotally secured by a pivot pin 45 and in a manner whereby the lever V 44 thereof is disposed in the path of a block 46 of a timer mechanism of the apparatus.

The block 46 is provided with a slot formed centrally therein and is mounted on an upfright 47 having projections 48 staggeredly j arranged thereon so ast-o retard the block in its downward movement as will be apparent, with the result considerable time is required for theblock to'descendV from the top of the upright until it engages the lever 44 for moving the latch on its pivot and thereby releasing the 'plate which will of course be Vvpulled and disposed above the compression chamber so as to cooperate with the-piston head for squeezing the contents of the bag in a manner which will be presently described. In view of the fact' that the rods 40 are loosely received in the hems 42 of the bag, it will be apparent that when the plate 28 is moved by its weight, the bag will be released from the rods.

In order to operate the piston and its head for pressing the bag against the plate 28 I have shown means for providing compressed air for this purpose, but I want it understood that any fluid pressure means may be provided, including hydraulic prese sure and the like. In the form as shown,

compressed air is adapted to bestored in a tank 49 having communication with a small portion of the compression chamber by .a pipe 50 whichvhas a control valve 51 arranged therein. The control valve is operated by the rod 52 having a knob 53 formed On'itsouter end thereof.- The tank 49 is supplied with air by a pump 54 which includes an vopen top cylinder.V and a piston as shown. The pump is operated from the motor 21 through the medium of a chain 55 which drives a disk- 56 having eccentrically mounted thereonva pin 57 for receiving the piston rod 58.V A suitable checkvalve is provided for the tank 49 and this check valve is disposed in a pipe line 59 which is likewise together with means for operating the same,

and dispensing means for the juice.

vWhen it is desired to operate the machine,`

the motor 21 is started, which puts the pump into operation for supplying the tank 49 with compressed air. The motor also operates the toothed rollersv 17 for grinding the fruit into pulp which of course is disposed in the bag 41. The timing block is disposed in its upl ermost position as shown in Figure 1 and by the time the block engages the lever 44,- the bag has 'received sufficient pulp from t-he grinding roller 17. then the timing block engages the lever, it will ofcourse dispose the latch to open position and release the plate 28 which will be arranged to cooperate with the piston head for pressing the juice from the pulp in the bag. .IvVhen the plate is moved, the cam member 62 will operate the handle 61 and release compressed air from the tank 49 into the combustion chamber, and the air -will operate the piston and its head. The pressing of the pulp in the bag 'will of course cause the juice from the pulp to pass into the container 4 through the medium of the openings of the enlarged portion of the combustion chamber and the juice can be dispensed from the container by the spigot 5.

The piston and its head is released by the control valve 51 which will allow the air .to flow back into the tank 49.

rIhe plate is provided Vwith a handle -63 whereby it can be disposed to its normal position against the pull of its weights and when so disposed, lthe cam member 62 will engage the operating handle 61 and dispose" the'same to its closed position as shown in Figure 1.
